Intelligently setting nominally-idle cells in a PIC photonic switch reduces crosstalk. 100Gb/s DP-QPSK simulation shows 0.3dB OSNR improvement, for 13dB extinction ratio of a practical photonic switch cell. The method operates correctly in a 10Gb/s NRZ test-bed.
Interoperability requirements are discussed for 200Gb/s PAM4 and verified using high-bandwidth electro-absorption modulated lasers (EML) and a concatenated forward error correction (FEC) scheme based on hard-decision zipper code, which can be applied to 800Gb/s-FR4 transmission.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
